Letters Patent No. 113,457, dated April 4, 1871.

rMPRovEMEN-r IN MOP-HEADS.

The Schedule referred to in 'these LetteraPatent and making p`art of the same.

To all lwhom it 'may concern:

Be it known that we, SAMUEL SELDEN and MAT- THEW .GRIsWoLD, Jr., of the city and county 'of Erie, State offennsylvania, have invented certain new and useful Improvements in Mop-Heads, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, in whichp Figure l is la perspective view of the improved mophead, and

' Figure 2 is a section .of the Same taken longitudinally of the pivoted Shanks.

Similar letters of reference denote corresponding parts in both figures.

A A are Iche jaws, each of whiclris semi-cylindrical in form, and provided on its outer or clampingedge with teeth a n', which engage with and securely hold the material of which the mop is made, as wllbe, readily understood.

B B are Shanks projecting at right angles from the jaws A A. VThese Shanks are also Semi-cylindrical in.

form, and are adapted to receive and inclose the end of a mop-stick or`handle.

Each of Shanks B B is expanded at its outer en( and formed into a lng; b, substantially as shown in the drawing, and is perforated to receive a pin or rivet, b.

Shank B' is provided centrally with a boss, C, in. which is out a screw-thread.

D is a thumb-screw passing through a Slot, b2, in shank B, and engages with the thread in boss C.

d is a spiral spring surrounding screw D, and serving to press the jaws A A' apart-when they are not held together by said screw.

E are socket-pieces, shown in full linesvin fig. 1 and in dotted lines in g. 2.

They are provided with ears e, by means of which they may be secured to the 'mop-Stick by a rivet, e', as represented in the drawing. l A

The central portion of each of the socket pieces is circular in form so as to iit the mop-stick, and each represents something less than a Semicircle, their ends e, forming wings, being turned outward ou nearly radial lines in Such manner that, when the parts are placed in proper position, as shown in the drawing,

the inner faces of these wings e2 shall be parallel with each other, and at such distance apart as will allow the lng b tc be placed between them, so that, when a rivet, b', is put in, the -parts E, e, b, andy b', form a hinge by which the' jaws A A are Vflexibly united to each other and may be ruily secured to stick F. v

rlhe construction and operation of these devices are so simple that a more extended description is not deemed necessary.

Having now described thie invention,

' What is claimed as new, and"sought to be secured by LettersPatent, is-

The combination of jaws A A', hinged Shanks B B',

andthumb-screw D', substantial] y as Set forth.
